MacHInERY FORZNAPPING CLOTH.

Specification of Letters Patent No. 11,105, dated June 13, 1854.

To all whom it may concern:

Be it known that I, JOSEPH WVEIGHT, of Lawrence, in the county of Essex and State of Massachusetts, have invented a new and Improved Machine for Napping Cloth and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had, to the annexed drawings, making a part of this specification, in

i whichbearings. r

Figure l, is a vertical longitudinal section of my improved machine, the plane of section being through the center. Fig. 2, is an end view of ditto. Fig. 3, is a detached View of the transverse belt.

Similar letters of reference indicate corresponding parts in the several figures.

This invention relates to a new and improved machine for raising a nap on cloth, and consists in the employment oruse of an endless card sheet in combination with a transverse card belt arranged and operating as will be hereafter fully shown.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

A, represents a box or case of suitable form, and having two transverse rollers, B, B, placed within it at about its center, the top roller, B, being near the top of the box or case, as shown in Fig. 1. Thetw'o rollers, B, B, are placed one above the other, a suitable distance or space being left between them. The top roller, B, should be so arranged as to be raised or lowered, and consequently its journals may lit in sliding C, is an endless card sheetwhich passes around the two rollers, B, B. The card is constructed in the usual manner, and therefore requires no particular description.

D, is a fly roller having leather strips, (on) attached to it, and shown in Fig. 1.

E, Fig. 1, is a belt which passes around one end of the upper roller, B, and around one end of the fly roller.

F, Figs. 1, 2, and 3, is an endless belt, having cards, (6), upon its outer surface. This belt passes around one end of the lower roller, B, and around a pulley, Gr, attached to the inner side of the box, or case, A, oppoprojecting from it as which said belt passes, see Fig. 3..

H, H, are transverse boxes or grooves at the upper part of the box, or case, A, in which boxes or grooves the belt, F, fits. At both ends of each box or groove, there is a roller, I, see Figs. 2, and 8, over which the belt passes.

J, J, are two rollers placed at one end of the box, or case, A, one roller directly over the other, and K, is a roller placed at the opposite end of the box or case, see Fig. l.

L, Fig. 1, represents a piece of cloth, having its ends secured together, and passing around the rollers, J J, and K, as shown in Fig. 1, the piece of cloth bearing upon the upper part of the endless card sheet, C, and endless transverse card belt, F.

M, is a belt which passes around a pulley, N, at one end of the roller, B, and around a pulley, O, at one end of the lower roller, J, see Fig. 2, and dotted lines in Fig. 1.

P, isa belt which passes around one end of theupper roller, B, and one end of the fiy roller, D, see Fig. 1.

Operation: Motion is communicated to the roller, B, in any proper manner, and the endless card sheet, C, moves in the direction indicated by the arrows, 1, and the endless transverse card belt, E, moves in the direction indicated by the arrows, 2, while the piece of cloth, L, is moved over the card, C, and endless transverse belt, E, by means of the belt, M, passing around the pulley, O,

i at one end of the roller, J, and the pulley, N,

at one end ofthe lower roller, B.

The belt, E, moves in reverse directions across the machine as denoted by the arrows, 2, in Figs. 2, and 3, and keeps the cloth properly stretched as regards width, and the cards, (6), onthe belt, E,act against the cloth, and with the endless card sheet, C, raise the nap on the cloth. The fly roller,

D, as it rotates, cleanses the card sheet, C.

The above machine works practically well, and renders the use of teasels unnecessary. The endless transverse belt, E, not only assists raising the nap, but also keeps the cloth, C, in proper position while passing over the card sheet, thus dispensing with the use of numerous guide rollers.

I do not claim the employment or use of cardsfornapping cloth, irrespective of the peculiar arrangement herein shown, for the manner and for the purpose as herein cards have been previously used, but shown and described.

What I claim as new and desire to secure by Letters Patent, is- JOSEPH WEIGHT 5 The combination of theendless card sheet, Witnesses:

C, and endless transverse card belt, E, the A. J. SHOVE, above parts being arranged and operating in ALFD. P. CLARK.
